Fuse problem:cannot understand what i'm missing

Hello fellow Audiogoners.I need your help.
A year ago i replaced a stock fuse on my Krell SACD mk3 (slow blow 500mA 20 mm (small)) with Hi-Fi Tuning fuse.
I threw away that Krell fuse thinking that i can always buy one at Radio Shack.I did some changes in my system and decided to try how Krell would sound with a generic fuse through my system.I went to Radio Shack and bought a 4 pack of Slow Blow fuses (T 500mA 250V).They all burned down one by one as soon as turned the power switch on.Everything is OK when i put back Hi-Fi Tuning fuse with the same specs.The fuses that burned down were slow blow fuses,500mA .I cannot understand why they are failing but a Hi Fi Tuning fuse keeps working without a problem.Are there any other specs that i'm missing?Please,help me solve this dilemma.Thanks a lot!

I don't think you're missing anything. Sounds like "slow" means something different to Radio Shack's supplier than it means to the other suppliers.

If you go to digikey.com or mouser.com (which are leading electronics distributors) you'll be able to find a wide selection of fuses from various makers, and I think the listings for them may provide links to data sheets which would indicate the specific blowing parameters.
